Calgary Board of Education


We work closely with Alberta Health Services to ensure that we are responding to cases of lice appropriately. If you receive an email from the school regarding head lice it is important for you to check your child for lice using the information in the attachments.

Some important things to remember about lice:

  • Head lice do not cause disease.
  • Head lice do not go away on their own. They must be treated.
  • Head lice are not a sign of poor hygiene.
  • Head lice do not hop or fly, they crawl. They are spread through direct head-to-head contact, or through sharing objects or clothing that come into contact with the head.
  • Research shows that head lice are not transmitted through classroom carpets.
  • Head lice can live up to 48 hours away from a human host. They cannot survive in the classroom over the weekend. If they recur in a classroom it is because a human host is bringing them back into the classroom.
  • Pets do not transmit head lice.
  • Children with head lice should be treated and can attend school or child care as usual. We do not exclude children from school due to head lice. We also do not isolate children or their belongings from the rest of the class because of head lice.
  • If we were to have head lice recurring in the same class or multiple cases of head lice in the same class we would work with Alberta Health Services and the families in question to ensure that we are responding appropriately.
